A Look at the Various Types of Commercial Roof Materials

No two businesses are alike, and neither are any two commercial roofs. Commercial roofs will differ from each other from the equipment they hold to the type of materials that make up their composition. Every kind of roof and roof material has its pros and cons. 

Here, we will look at some of the most common types of materials used on commercial roofs and explore the advantages and disadvantages of each one:

Polyvinyl Chloride Membranes

Known in the roofing business as PVC, Polyvinyl Chloride Membranes are one of the most popular commercial roofing materials. PVC roofs are made up of two layers of roofing material with a polyester layer in the middle for reinforcement. PVC is popular because it is extremely durable and long-lasting. It is also resistant to fire and moisture. The main downside is that PVC can be expensive compared to other roof materials. The material can also be difficult to repair when it ages.

Ethylene Propylene Diene Monomer

EPDM is commonly known as rubber roofing. This roofing material is easy to install, lightweight, long-lasting, and is one of the most inexpensive roofing materials. While EPDM roofs will last a long time in perfect conditions, they do puncture easily. Rubber roofs can also spring leaks easily if they are not properly adhered and leaks are difficult to detect in this material. EPDM is also not considered to be very aesthetically pleasing for buildings where the roof will be visible.

Metal Roofs

Many different kinds of metal can be used in commercial roofing from copper to galvanized steel to aluminum. Each type of metal has its own advantages and disadvantages but, generally, metal roofs are among the most durable and long-lasting roof options. Metal opens up a whole world of design options for a building, and the material is usually used for buildings where looks are a concern. Metal roofs also tend to be more fireproof than other types of roofing material, but it can be expensive.

Thermoplastic Polyolefin

In most cases, thermoplastic polyolefin, or TPO, is the cheapest roof material available. TPO is similar to both PVC and EPDM, but it is 100 percent recyclable. TPO is a lightweight membrane that is typically heat-welded at the seams rather than adhered like EPDM—however, it can also be mechanically fastened. This welding makes TPO more resistant to leaks than EPDM, but the material also has many disadvantages. TPO is prone to shrinking and cracking. The material is also not fire-resistant. 

Spray Polyurethane Foam

SPF is a plastic that is sprayed out as a foam that then solidifies and expands over a rooftop. This foam seals off gaps on the roof and is extremely insulated, helping owners save on energy bills. SPF is typically layered onto a roof underneath another roof coating. Applying SPF is a specialized skill, and not all roofing companies offer it. Applying and maintaining this material can be expensive.

Because this type of roof is difficult to repair and replace, Maxwell strongly recommends against having this type of roofing material installed. 

Asphalt

Asphalt is an older method for commercial roofs. The material is rolled out and pressed onto a roof deck. Asphalt roof systems are typically more expensive than PVC, EPDM, and TPO but are also more durable and long-lasting. They are very tough and puncture-resistant due to the multiple plies included in the system. This type of material is recommended for manufacturing plants or any roof that will have roof traffic or penetrations.

5 Eco-Friendly Commercial Roofing Options to Consider

Companies decide to go green for many reasons. It may be due to a core business value or for a chance to connect with customers. It may just be for the cold hard cash savings that come from energy efficiency. Whatever the reason for becoming more eco-friendly, facility managers shouldn’t overlook the importance of choosing the right type of roof to maximize energy savings and eliminate waste. Here are five environmentally-friendly options for commercial roofs:

  1. Solar Panels—The large empty space on a commercial roof is the perfect place to put solar panels to offset a building’s electricity use. New roofs can be specially outfitted to support the weight of solar panels. Older roofs will likely need some modification to safely secure panels on the roof. Though a solar company may say they can install the panels, it’s important to always use a professional roofer to ensure that the installation doesn’t do any damage.
  2. Green Roof—Not only do roof plants help fight climate change, but they also can help moderate the temperature of a commercial building and improve air quality in the surrounding area. Green roofs are ideal for urban areas where there is little other surrounding vegetation.
  3. White Roof—Roofs with white or light-colored membranes are considered “cool roofs” because of their ability to reflect more of the sun’s rays away from the building. In hot places, cool roof systems can help reduce the need for air conditioning in the summer, lowering the building’s electricity bill.
  4. Metal Roof—Metal is one of the most eco-friendly materials for roofs. A metal roof made from recycled materials can last up to 60 years, and the material can be re-used again once it is time to replace it. Metal is also reflective, keeping buildings cool in the summertime.
  5. Recycled or Biodegradable Roof Material—There are plenty of ways to use recycled or biodegradable materials for a more traditional commercial roof style. Reclaimed clay can be used in tile roofing. Sustainably harvest wood shake is biodegradable and can be used for shingles. Old tires can also be made into rubber roofing material that can last for many years.

When choosing the right eco-friendly roofing for any building, it’s important to always use a professional roofing company.
